[Possibilities for reproducing stereoscopic images on monitors in relation to the surgical microscope]

A variety of systems, including open-sight systems, can be used in combination with an operating microscope to reproduce stereoscopic images on a monitor. All these systems have the disadvantage that they disturb the free interplay of accommodation and convergence, and in the long term this can be tiring for the observer. A method similar to holography might be an ideal open-sight method for imaging the surgical procedure three-dimensionally.
